Are Speed Guns Accurate Enough for the Court?

Police and traffic enforcers can apprehend drivers for a number of misdemeanors. For cases such as speeding, the car’s speed is the only evidence an enforcer may use. While most states allow the use of speed gun results in court, there are certain limitations to it that a driver can challenge when charged with speeding.

Speed Guns in the Wrong Hands

If a driver discovers that an unqualified enforcer used a speed gun, he or she may challenge its results. Officers who use speed guns must pass an approved and certified training program before they can handle one.

If a driver’s state requires this, he or she might look at the officer who issued the ticket. If the officer is uncertified, the driver can argue that the speed gun’s results are faulty due to the operator and not because they were speeding.

Faulty Calibration Schedules

Another way drivers may challenge the speed gun’s results is to check for its calibration and quality. To achieve the best results, enforcers must schedule a calibration of their speed guns. Sometimes, this is scheduled by the state.

Calibration requires adjusting and a tuning fork test to provide accurate readings. If enforcers do not use a tuning fork or do not follow the speed gun’s calibration schedule, drivers can challenge the speed gun’s results as faulty evidence.

Using the Best-Quality Speed Gun

These aspects do not focus on the speed gun itself but the person using and maintaining the speed gun. However, the reliability of a substandard speed gun that cannot promise accurate results may also be questioned in court.

When it comes to purchasing speed guns, police, traffic enforcers, and other authority figures on the road must choose high-quality speed guns for accuracy and precision. Many speed gun brands stand out in the sports industry and police sector, providing accurate results for many years.


Two forms of speed gun technology exist in the market, both with its own way of detecting speeds. LIDAR (Light Detection and Ranging) guns use rapid laser signals to record the time it takes for lasers to bounce back from the obstacle, measuring speed and distance. RADAR (Radio Detection and Ranging) guns work similarly, except with radio waves.

While both are effective in detecting speeds, LIDAR guns provide more accuracy, and its technology trumps illegal radar jammers used to distort the waves to record a speeding vehicle. Officers and enforcers should continue to use high-quality LIDAR guns. Brands such as DragonEye, which provide speed guns to military and private security firms, provide accurate results.

Enforcers continue to use speed guns in a court of law since its accuracy in recording speeding violations remains generally infallible. While some human error may put its accuracy and vulnerability at risk, high-quality speed guns can still provide reliable evidence.
